arms cartridges, and has for its object to. provide a devlce of thischaracter whloh embodies novel features of construction whereby theseveral steps of the stamping are simultaneously performed at eachoper..

ation or revolution ofthe main drive shaft,

thereby completing a cartridge at each re' volution and enabling largequantities .of

Further objects 0 which is simple in its construction,which provides forautomatically feeding the cartridges through the machine as the stampingof repair or adjustment and which'provides for adjusting the automaticfeed of the die blocks so that the movement thereof will be in exactvsynchronism with the up and down movements of'the punches.

With these and other objects 1n vlew, the 111V6nt1011 consists 1ncertain novel combinations and arrangements of the parts as will-morefully appear as the descrlptlon proceeds, the novel featuresthereofbeing pointed out in the appended'claims."

I

Referring. to the drawings, which illustrate one embodiment of theinvention, the

numeral 1 designates a table which may be drive shaft 9 whichisho-rizontally disposed j and is journaled' in suitable bearings 10provided on the frame 5. Fly wheels 11 are applied to opposite endsfo fthe main shaft 9 and power may be applied to this shaft in any suitablemanner. It will be obvious that as'the shaft is rotated the cross head 6will be moved up and down, and one end of the shaft is provided with aneccentric 12 which operates the means for feeding the die blocks. a I IA series of punches '13 project downwardly from the cross head 6, saidpunches" successively m'creasing in length in the d1-,

rection in which the die blocks travel, and

being properly shaped to, perform the successive stampingoperationswhich are re-- quired "to complete the cartridge. Ordrnarilyiseve'n stamping operations are re quired for this purpose, and inth'e'present instance the crOsshead-G is provided with.

seven of the punches 13 which project downwardl'yi therefrom andgradually increase 1n length from one end. of the cross head to theopposite end thereof. Each of the die blocks 4: is also provided withseven the openings 14, said die openings being spaced in a mannercorresponding to the spacing of the punches 13, and the feedingmechanism being arranged to impart a step by step movement to the dieblocks so that in the operation of the machine each of the die openings1% is brought successively under the several punches 13. Since all sevenof the stamping operations are accomplished at each revolution of themain shaft, it will be understood that one complete cartridge will beturned out at each operation of the machine, thereby enabling largequantities of the cartridges to be manufactured and turned out completein a short period of time. The die blocks 4: travel in the groovedguideway 3, being provided with side flanges 15 of which one is toothedto form a rack, and which travel under flanged guide strips 16 securedto the top of the table. The guide blocks are thus free to travellongitudinally across the table,

although they are held securely against lateral displacement, and theflanged guide strips 16 prevent them from being lifted up with thepunches.

The toothed side flanges or racks 15 of the die blocks are engaged by apinion 17 at the upper end of a vertical shaft 18, the lower end of thevertical shaft being connected by bevel gearing 19 to a horizontal shaft20 which has a ratchet gear 21 fitted thereon. This ratchet gear is ofthe conventional construction, being locked with the shaft to rotate thesame when turned in one direction, and turning independently of theshaft in the other direction. An oscillating gear wheel 22 meshes withthe ratchet gear 21, and is connected by a pitman-23 to a crank disk24:. A slide 25 extends diametrically across the face of the crank disk24 and carries a wrist pin 26 which is engaged by the lower end of a camrod 27, the upper end of the cam rod being provided with a strap 28which extends around the before mentioned eccentric 12 of the main driveshaft 9. The ends of the slide 25 terminate in threaded stems upon whichnuts 29 are threaded, thereby providing for looking the slide and wristpin 26 in an adjusted position. As the main shaft 9 revolves theeccentric 12 reciprocates the cam rod 27 and this oscillates the crankdisk 24, the amplitude of the oscillation depending upon the adjustmentof the wrist pin 26, becoming greater as the wrist pin is moved awayfrom the center of the disk. This movement of the crank disk 2% istransmitted to the oscil-.

lating gear 22 through. the pitman 23, with the result that the ratchetgear 21 is rotatedback and forth to produce an intermittent or step bystep movement of the die blocks across the top of the table 1.. Byadjusting the position of the wrist pin 26 the movement of the dieblocks can be brought into exact synchronisni with the movements of thepunches, and the adjustment is such that the die blocks remainstationary while the punches are lowered into the die openings 14,although they are advanced a distance equivalent to the spacing betweenthe punches each time the punches are raised. The several die openingsare thus brought successively under the different punches 13, with theresult that the metal therein is properly stamped and shaped, the lastpunch being constructed to project the completed cartridge shell fromthe machine, and one complete cartridge shell being produced at eachreciprocation of the cross head.

The die blocks 4 are arranged end to end and have a detachable pivotalconnection so that they are fed through the machine in the form of acontinuous chain, thereby avoiding all unnecessary handling of thematerial. One end of each of the die blocks is formed with a tongue 30,while the opposite end thereof is correspondingly recessed at 31, thetongue of each block being received within the recess of the adjacentdie block and connected thereto by a pivot pin 32 which passes looselythrough corresponding openings therein. The connection between the dieblocks is such that a proper spacing of the die openings 14 in the chainof die blocks is maintained throughout the length thereof, and the dieblocks can be readily detached from each other at one end of the chainand connected at the opposite end of the chain. The operation of stamping the cartridge blanks is thus enabled to be performed rapidly, sincethe seven necessary stamping operations are performed at one timeinstead of successively, and the output of an operator is thus greatlymultiplied.

A slight modification is shown by Fig. 9, in which an idler 37 isinterposed between the pinion 17 and the rack 15 of the die block. Thisextra pinion provides for'increasing or decreasing the speed with whichthe die blocks move, as may be necessary when the cartridge press isoperating under different conditions.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is
